I have a wall clock (distant cousin to grandfather clock) that I need to wire to be able to turn on and off during the show as the characters make ongoing comments about the time on the clock. The clock has one AA battery for the time and one AA battery for the pendulum. I only have big box stores and local radio shack for parts. I have not worked with small voltage DC devices before so I need a little help on best configuration. I thought to use doorbell wire and solder it to the corresponding contact points on the clock and bring them out to a AA battery pack with some sort of switch between….tried it…didn’t seem to work that well. Will a 1.5V converter work? any advice?
